What statement about blueprints is true?

• A. Blueprints are decorative only.
• B. Blueprints are used to communicate manufacturing information.
• C. Blueprints are obsolete.
• D. Blueprints are used only for assembly diagrams.

Answer: (B)

Blueprints are the language of manufacturing, conveying every specification a part needs to be made. They communicate manufacturing information: exact dimensions, required tolerances, material type, surface finish, heat treatment, thread details, finishes, and any assembly or inspection notes. This ensures the part is produced consistently and can be checked against the drawing. They are not decorative, they are not obsolete, and they are not limited to assembly diagrams; a blueprint can show both individual part features and the notes on how parts fit and are manufactured.
